Reading a sustainability claim

Ask three questions before accepting any green claim. What percentage is recycled, by weight or by fibre? Is there a transaction certificate that follows the batch, not just the mill? And is the finish PFAS-free, because a recycled bag finished with long-chain fluorocarbons has simply moved the problem downstream. We answer all three in writing before production starts.

What recycled content actually means

Recycled content can be measured two ways and the difference is large. Post-industrial recycled material comes from production offcuts and is comparatively easy to source and certify. Post-consumer recycled material comes from used products and is the claim most buyers actually want, but it requires a documented chain from collection through reprocessing to yarn or film. A bag described simply as recycled without saying which will usually be the former.

The evidence that separates a real claim from a marketing one is a transaction certificate tied to the batch, not to the mill. A mill-level certificate says the mill has recycled capacity; a transaction certificate says your specific lot contained it. Ask for the latter, check that the quantity on the certificate matches the order, and file it — regulators in the EU and several US states now treat vague environmental claims as actionable. The EPA and the European Chemicals Agency both publish guidance on what evidence a claim needs; check the current text before artwork goes to print.

PFAS-free finishes: what you give up

Fluorinated durable water repellents were the default for decades because they work well and last. They are also the reason outdoor gear has shown up in drinking water studies, and long-chain variants are now restricted. Water-based and silicone alternatives are available and perform acceptably, but they are not equivalent.

Read that table as a performance budget, not a problem. A dry bag gets its water resistance from the film, not from the finish; the finish only keeps the face fabric from wetting out and gaining weight. Choosing a PFAS-free finish costs you some spray performance on the outer face and costs the end user a retreatment once a season. It does not compromise the waterproof function of the bag.

Documentation you should demand before production

Five documents, and none of them should be a generic company statement.

1. Transaction certificate for the recycled content, batch-matched to your order quantity, issued under a recognised standard.
2. REACH SVHC statement covering the finished article, not just the fabric, because hardware and print inks are in scope.
3. RoHS screening on metal and plastic trims, since buckles and D-rings are the parts most likely to fail a screen.
4. PFAS-free declaration naming what was substituted, because ‘PFAS-free’ alone does not say which chemistry replaced it.
5. Hydrostatic test data from the production batch, so you can confirm the recycled build performs to the same figure as the conventional one.

If a source cannot produce the third and fourth items, the recycled story is not yet backed by the trim supply chain, and claiming it on the finished product is a risk you would be carrying alone.

End-of-life and repairability

A recycled bag that cannot be repaired is a partial answer. Welded TPU construction can be re-welded with the right equipment, which means a punctured panel can be replaced rather than the whole bag discarded. Design choices that help: single-polymer construction where the film, face fabric and webbing are all from the same polymer family, hardware that is removable rather than permanently bonded, and no mixed-material laminates that cannot be separated at end of life.

Print method matters here too. A heat-transfer logo on a recycled TPU face is recyclable with the bag; a PVC plastisol print is not. If the recycled claim is central to the product, specify the print method at the same time as the film.

Cost, minimum order and lead time

Recycled film and rPET face fabric add roughly 12 to 20 percent to material cost at current volumes. Most of the rest of the difference is administrative: batch-level documentation is work, and it has to be done per order rather than once. Lead times lengthen only when recycled yarn has to be ordered specifically; the common rPET grades are stocked, as is recycled TPU film in the standard thicknesses.

Minimum order is 500 pieces per colourway, sampling 6–10 working days, bulk 35–50 days, FOB Xiamen, T/T 30/70, inspected to AQL 2.5.

Cost and lead-time reality

Recycled film and rPET face fabric add roughly 12 to 20 percent to material cost at current volumes, and both need batch-level documentation, which is administrative work rather than technical work. Most buyers absorb it because the recycled story is worth more than the margin difference at retail. Lead times lengthen only when recycled yarn must be ordered specifically; the common rPET grades are stocked.

A word of caution on marketing: a recycled badge with no transaction record behind it is a liability, not an asset. Regulators in the EU and several US states now treat vague environmental claims as actionable, so plan the documentation pathway before artwork goes to print.

Frequently asked questions

Are recycled dry bags as waterproof as standard ones?

Yes. Recycled TPU film is tested to the same hydrostatic head figures as virgin film at equal thickness, and it welds in the same process window. The waterproof performance comes from the film and the seam, neither of which changes with recycled content.

What does PFAS-free mean on a dry bag?

It means no fluorinated compounds were used in the durable water repellent finish. The finish keeps the outer face fabric from soaking up water; it is not what keeps the bag watertight. PFAS-free finishes need retreatment sooner but do not compromise waterproofness.

How do I verify a recycled content claim?

Ask for a transaction certificate matched to your batch quantity, not a mill-level certificate of capacity. Check that the quantity on the certificate matches your order and file it with the shipment documents.

Is recycled TPU more expensive?

Yes, typically 12 to 20 percent on material at current volumes. The recycled yarn and film are stocked in common grades, so lead time is affected only when a specific grade has to be ordered in.

Can an eco-friendly dry bag be repaired?

Yes. Welded TPU construction can be re-welded with the right equipment, so a damaged panel can be replaced. Specify single-polymer construction and removable hardware to keep that option open at end of life.

Which compliance documents come with a recycled order?

A transaction certificate for recycled content, a REACH SVHC statement on the finished article, RoHS screening on trims, a PFAS-free declaration naming the substitute chemistry, and hydrostatic test data from the production batch.
